Anyone know of a PCIe x1 2.5GBe NIC?

As the title says, does anyone know of a PCIe x1 slot, 2.5GBe network card? I have found this Intel based I225-V 2.5Gbps Ethernet PCI Express Card RJ45 LAN Adapter Converter. Any other options or opinions? I don’t need a enterprise level of performance. Currently I have a vdev of 8 wide 3TB WD Reds with a 1GBe realtek NIC (built in). Hoping to get some better throughput. I am limited to x1 PCIe unfortunately however.

Any PCIe card that will physically fit in the slot should be compatible with x1 electrical, even if it’s x2 etc.

x1 at PCIe2 speed is good for about 500MB/s iirc, which means plenty for 2.5gbps.

And at PCIe3 speeds… about 1GB/s per lane.

I’d go with the intel adapter.

Actually, I’d go with an intel 550-T2 10gbe adapter.

But anyway.

Thanks for the reply. Yeah, I’d go for the 550-T2 but its nearly $300 more. Not worth it for my use case. A single 2.5GBe is plenty for my needs. Thanks again

Its 99$

Yeah, that’s $166 in my dollars mate. Still way too much as I need two of them and a switch for my setup.

I’m using an i226 pcie x1 based 2.5Gbe adapter on a smaller TrueNAS server, it has worked without issues and indeed it’s nice to not waste a bigger slot on a NIC (most pcie x1 slots don’t have the “open back” needed to fit a bigger card)

if you are buying a new card, buy the i226 and not the i225.
